The Lowdown
Alright, let me tell you how things are shaping up for Kennebunk Beach.
Look, I’ll be straight with you – it’s a tough stretch ahead. We’ve got a solid 16-day window here, but the surf is looking pretty sad for most of it. You're gonna have to be patient. There's a big gap right from the start; the first few days are a write-off. The energy is just too weak and the conditions are messy.
We finally see a little pulse of energy coming in around Wednesday, September 2nd, with a combined swell energy hitting 106 (moderate) but the wind is on it and the period is short at 6 seconds, making for choppy, junky waves. The biggest bump we see in terms of size comes on Saturday, September 5th, when a 3ft swell from the ENE shows up with a clean, cross-offshore wind. The combined energy is 139 (moderate). But the water temperature is 67°F, which is a touch warmer than normal for this time of year – a nice little bonus if you’re keen for a paddle.
The closest thing we have to a standout is on Sunday, September 6th. The morning is a bit blown out with a 4ft ENE swell and strong wind, but by the afternoon things clean up. We get a 2ft swell from the ENE with an offshore wind and a long period of 11 seconds. The combined energy is 198 (moderate). It’s not huge, but with that offshore breeze and the longer period, it’ll be the most lined-up and cleanest wave of the whole run. The ENE direction is right in the sweet spot for Kennebunk Beach. If you only get one session, that Sunday afternoon is it. Just be aware, it’s a fairly consistent spot, so there will be a few others out.
After that, it fades back to tiny, weak dribble for the second week. There are a few glassy mornings, like on September 11th, but the swell is barely 2ft with weak energy (68). You’d be chasing ankle-biters. Honestly, for most of this forecast, it’s more of a lake paddle than a surf. Hang tight and keep an eye on the charts.

The above surf forecast table for Kennebunk Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kennebunk Beach can be found by selecting the local surf guide option on the grey menu. Our Kennebunk Beach surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period.

Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Kennebunk Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
